4 Motor shaft rotation direction (connectionless)

Press to turn the tester on. The green diode should go ON
signalling that the device is ready for operation.

Put the rear part of the TKF-13 tester to a working motor along its
axis (the position of the axis in accordance with the adjacent illus-
tration). The distance between the tester and the motor should not
exceed 2-3 cm.

The light of the R diode means the motor shaft spins clockwise.
The light of the L diode means the motor shaft spins anticlock-
wise.

Lack of indications (diodes L and R are off) may mean the motor
is not working or the signal is too weak.

In case of certain single-phase inductive motors, indica-
tions may be hindered.

The device has not been designed for the purpose of
tests of single-phase commutator motors.

The device has not been designed for the purpose of
tests of motors powered through electronic power con-
verters (inverters).
Below there is a diagram illustrating the minimum motor diameter for the given revolution and the fre-
quency of the mains at which the indications of the tester are reliable.
